Eine brennendste Zeitfrage allerdings! Es brennt in allen Ecken und Enden der ethnologischen Welt, brennt hell, lichterloh, in vollster Brunst, es brennt ringsum, Gross Feuer! und Niemand regt eine Hand.A most burning question of time, though. It burns in every nook and cranny of the ethnological world, burning, bright, brightly, in the fullest blaze, and it burns all around, huge fire! and no one lifts a hand.[Expressing his desperation over the loss of the cultural memory of ethnic traditions as so many cultures were no longer living in isolation.]

Wilderness is an anchor to windward. Knowing it is there, we can also know that we are still a rich nation, tending our resources as we shouldnot a people in despair searching every last nook and cranny of our land for a board of lumber, a barrel of oil, a blade of grass, or a tank of water.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
